I was wearing my hacker jacket in downtown SF the other day while hanging out with the new work crew walking back to the office from lunch, and as I'm crossing the street I hear "Hack the planet?! YEAH! Hack the planet!" and realized someone had seen the hack the planet patch on my jacket ... so arm raised I shouted "HACK THE PLANET!" and someone else also did the same (no idea who, they were across the street). Hell yeah, HACK THE PLANET!
